| Abstract: |
| This study was conducted to investigate the effects of organic fertilizer containing bio-fertilizer on continuous crop disorders, poor vegetable growth, and soil nutrient imbalance caused by unreasonable fertilization when planting vegetables in facilities. Five treatments(a blank control, traditional fertilization, single application of bio-fertilizer, organic fertilizer with bio-fertilizer, and liquid organic carbon with bio-fertilizer)were set up through field experiments, focusing on the effects of different fertilization treatments on the basic chemical properties of soil, soil enzyme activity, the growth condition of facility vegetables, and the structure of the vegetable soil microbial community. The effects of organic fertilizer with bio-fertilizer on soil fertility quality, field growth of vegetables, and the microecological environment were studied. Treatment with organic fertilizer containing bio-fertilizer increased chlorophyll by 6.04% and 8.74%, respectively, compared to the blank control and conventional fertilizer treatments, and significantly increased the fast-acting nutrients and enzyme activities in the soil by a maximum of 22.80% and 43.88%, respectively. The treatment with a single application of bio-fertilizer increased the number of bacteria and actinomycetes(11.96% and 9.39%, respectively). It decreased the number of fungi (21.54%)in the soil compared to the conventional application, improving the soil microbial structure and enriching the bacterial diversity, which helped to reduce the occurrence of soil-borne diseases in facility vegetables. Organic fertilizer with bio-fertilizer is more helpful in achieving an optimized effect on the soil-plant-microbial system, which is more beneficial in enhancing the quality of the environment and increasing the diversity of soil microorganisms compared with other treatments, whereas bio-fertilizer alone is also able to enhance the number of soil microorganisms. |
